I have an HP PSC 2355 printer, it worked OK on Tiger although it never finished its setup properly and would comne up with the same annoying message each time at Startup. Things have only got worse since I installed Leopard - now I get a message saying 'The application HPIO Trap Monitor quit unexpectedly' every 3 minutes or so. I have tried uninstalling and reinstalling to no effect, drivers seem to make no difference though I really don't know which ones (if any) I should be installing. Any suggestions? I would receive them very gratefully!
